Combined type joint and bronchus blocking sleeve with same

Abstract

The invention discloses a combined type joint (1) and a bronchus blocking sleeve with the he combined type joint (1). The combined type joint comprises an upper interface (1-1), a lower interface (1-6) and a side interface (1-5). The bronchus blocking sleeve with the combined type joint comprises a bronchus blocking guide pipe (2), a trachea cannula (3) and the combined type joint (1), wherein the bronchus blocking guide pipe (2) penetrates through the trachea cannula (3); and the combined type joint (1), the bronchus blocking guide pipe (2) and the trachea cannula (3) are in detachable seal connection. The combined type joint can be immediately connected with a breathing machine for carrying out postoperative care just by drawing the upper half part of the combined type joint (1) and thebronchus blocking sleeve (2) without secondary insertion after double-lung isolating operation. The unique design of the invention can be convenient for the clinical operation of the operation greatly.

Description

Technical field [0001] The invention belongs to the field of medical devices, and in particular relates to a combined joint and a bronchial plugging sleeve with the joint. Background technique [0002] One-lung ventilation (OLV) is a commonly used method of airway management in modern thoracic surgery. Even if one lobe of the patient stops breathing, the other lobe inhales oxygen to maintain the body’s needs, so as to isolate the patient’s lungs and separate both lungs. Ventilation, bronchoalveolar lavage, or lateral lung collapse. Two-lung isolation can prevent secretions, infection sources, blood or abscesses from one lung (operating lung) from entering the other lung (key-side lung), so as to protect the lungs. In unilateral lung surgery, thoracoscopic surgery, and esophageal surgery, the operative side alveoli are collapsed to facilitate surgical operations, and it can also prevent secretions and blood from the operative side lung from flowing back to the contralateral lung....

AI Technical Summary

Problems solved by technology

The guide lumen of the Univent single-lumen double-bag broncho-occlusion catheter is also larger, resulting in fewer effective ventilation lumens

The Arndt bronchial obstruction catheter better compensates for the shortcomings of the above two types of catheters with fewer effective ventilation channels, but it must be used under the guidance of a fiberoptic bronchoscope, which limits its scope of application in hospitals
